234  * so we need to do lots of extra work to try to get to this clipboard data.

237  *  1. On keydown with paste keys Ctrl+V or Shift+Insert create
238  *     a paste bin element and move focus to that element.
239  *  2. Wait for the browser to fire a "paste" event and get the contents out of the paste bin.
240  *  3. Check if the paste was successful if true, process the HTML.
241  *  (4). If the paste was unsuccessful use IE execCommand, Clipboard API, document.dataTransfer old WebKit API etc.
